used to be my main language - I can most likely help you with almost anything related to C#, although I have less experience with dynamic and async here as I don't like the concept of dynamic typing in .net and I use F# for my asnyc needs.

I am well versed in the basics and some of the more advanced topics in Haskell. So I would love to help you understand the fundamentals of this language and functional programming in generals.
But I sadly lack professional experience of using Haskell at work.
